Hi,
I've been searching and trying things but to no avail yet.
This is uncritical because it's a test cluster only, but I'd still
like to have a solution in case this somehow will make it into our
production clusters.
It's an Openstack Victoria Cloud with Ceph backend. If one tries to
remove a glance image (openstack image delete {UUID}' which usually
has a protected snapshot it will fail to do so, but apparently the
snapshot is actually moved to the trash namespace. And since it is
protected, I can't remove it:
storage01:~ # rbd -p images snap ls 278ffe2b-67a7-40d0-87b7-903f2fc9c3b4 --all
SNAPID NAME SIZE PROTECTED
TIMESTAMP NAMESPACE
159 1a97db13-307e-4820-8dc2-8549e9ba1ad7 39 MiB Thu
Dec 14 08:29:56 2023 trash (snap)
storage01:~ # rbd snap rm --snap-id 159
images/278ffe2b-67a7-40d0-87b7-903f2fc9c3b4
rbd: snapshot id 159 is protected from removal.
storage01:~ # rbd snap ls images/278ffe2b-67a7-40d0-87b7-903f2fc9c3b4
storage01:~ #
This is a small image and only a test environment, but these orphans
could potentially fill up lots of space. In a newer openstack version
(I tried with Antelope) this doesn't seem to work like that anymore,
so that's good. But how would I get rid of that trash snapshot in this
cluster?
Thanks!
Eugen
